No one has the right to do wrong, even if wrong has been done to them.

For the world is in a bad state, but everything will become still worse unless each of us does his best.

It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life—daily and hourly. Our answer must consist, not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual.

Everything can be taken from a man but one thing: the last of the human freedoms—to choose one’s attitude in any given set of circumstances, to choose one’s own way.

A man's concern, even his despair, over the worthwhileness of life is an existential distress but by no means a mental disease.

What is demanded of man is not, as some existential philosophers teach, to endure the meaninglessness of life, but rather to bear his incapacity to grasp its unconditional meaningfulness in rational terms.
